SPECIFICATION formingpart of Letters Patent No. 516,325, dated March 13,1894. Application filed December 12, 1892. Serial No. 454,904. (Nomodel.)

To aZZ whom it may concern:

Be it known that we, l/VILLIAM WOMERS- LEY, GEORGE SAGUE, and MORTIMERA. OLAPP, citizens of the United States, residing at Poughkeepsie, inthe county of Dutchess and State of New York, have invented new anduseful Improvements in Paper-Feeding Machines, of which the following isspecification.

This invention relates to paper feeding machines which feed sheets ofpaper successively from a pile to a printing press, ruling, folding,calendering or other machines in which sheet paper is operated upon.

The objects of this invention are to render the machine suitable for usein connection with a printing press when the space is extremely limited;to improve the buckling mechanism by which the top sheet is loosened andthe mechanism by which the feed table is raised automatically, in suchmanner that the pile of paper is not crowded out of its normal positionby the action of these devices and to improve the machine in variousdetails of construction. I

In the accompanying drawings consisting of seven sheetsz-Figure 1 is aside elevation of our improved paper feeder attached to a printingpress. Fig. 2 is a top plan View thereof. Both of these figures aredrawn to a reduced scale. Fig. 3 is a fragmentary side elevation of theupper portion of the paper feeder, viewed from that end of the machineon which the mechanism is arranged which raises the feed table. Fig. 4is a sectional elevation of one of the feeding fingers and Fig. 5- is aside elevation side of the machine. Fig. 6 is a vertical transversesection in line 6-6, Fig. 5.

Fig. 19 is a face view of one of thesegmental gears whereby motion is transmitted to the feed regulator.Fig. 20 is a perspective view of one of the rear clamps which connectthe longitudinal rod with the transverse rod on which the upper guiderollers are hung.

Like letters of reference refer to like parts in the several figures.

A A, represent the upright side frames of the machine which areconnected at their upper portions by front and rear cross rods a a, andat their rear ends by upper and lower cross stays 0; a respectively.

B represents the vertically movable feed' table, upon which the pile ofpaper is placed, and which is provided with laterally projecting screwnuts I) b which are guided in upright ways formed on the side frames.

b I) represent the vertical feed screws which work in the screw nuts I)b of the feed table. The feed screws are provided at their upper endswith bevel wheels 5 which are connected by a horizontal transverse shaftb journaled at the upper ends of the side frames and having bevel wheels5 b which mesh with the wheels of the feed screws so as to actuate bothfeed screws simultaneously.

0 represents upright front guides which engage against the front side ofthe pile of sheets, and O are side guides which engage against the sidesof the pile of sheets.

As represented inFigs. 1 and 2 the paper feeder is connected with aprinting press having a revolving impression cylinder D, and ahorizontally reciprocating type bed D. In a press of this kind the bedis usually inclosed on both sides, the inclosure not being shown in thedrawings, and the bed is therefore inaccessible from the sides and onlyits front end is open to permit of making the type forms ready on thereciprocating bed. In order to afiord access to the front end of thepress through the lower part of the paper feeder, the front guides O aremovably supported on the cross stays a a. in such manner that they canbe moved laterally out of the way. For this purpose the guides areprovided with loops cl embracing the upper cross stay a and with hooks dformed on the lower ends of the guides and embracing the lower crossstay a as represented in Figs. 8, and 15.

E E, Figs. 7, 8, and 9, represent two movable heads carrying thebuckling mechanism,

one of which is arranged on each side of the machine so as to buckle thesheet simultaneously from opposite sides. These two heads are arrangedupon the front ends of the longitudinally adjustable rods 6 which latterare secured withtheir rear portions to the cross rods a a by front andrear clamps 6' e Each of these clamps consists of a longitudinal sleeve6 which receives the longitudinal supporting rod 6 and a transversesleeve 6 arranged below the longitudinal sleeve and receiving thetransverse rod, the front transverse sleeve receiving the transverse rodon and the rear transverse sleeve the transverse rod a. The upper sleeveis split on one side of the longitudinal rod and the lower sleeve issplit on one side of the transverse rod, and both sleeves of the sameclamp are tightened upon their respective rods by vertical hand clampingscrews 6 Upon loosening the hand screws 6 the buckling mechanism can beadjusted longitudinally in the machine by sliding the rod 6 in theclamps and the buckling mechanism can also be adjusted transversely inthe machine by sliding the clamps on the cross rods a a so that by thesetwo adjustments, which are effected at right angles to each other, theentire buckling mechanism can be adjusted to the corner of the pile ofsheets on the table.

F F represent longitudinal rock shafts whereby motion is imparted toeach buckling mechanism and which are journaled with their front ends inthe carrying heads E and with their rear ends in bearings ff formed incarrying frames F which latter are pref erably formed integrally withthe front clamps e as shown in Figs. 7, S, and 15.

G, G, represent two groove cams which are mounted upon a transversecounter shaft 9 journaled near its ends in the side frames. Each ofthese groove cams is secured to the counter shaft by a feather g whichcompels the cam to turn with the counter shaft but permits it to slidelengthwise on the same. The groove cam is compelled to move transverselyin the machine with the carrying frame by bearings g g formed on thecarrying frame and supporting the counter shaft on opposite sides of thegroove cam.

g? represent rock arms secured with their lower ends to the rock shaftsF between the bearings f f by feathers g and provided at their upperfree ends with anti-friction rollers g which engage with the grooves ofthe cams G. The grooves in the latter are reversed as represented inFig. 2, so that upon turning the counter shaft an oscillating motion, inopposite directions, is imparted to the rock arms and shafts F, g

H, Figs. 3, 7, 8 and 9 represents the buckling finger pivoted to thelower end of a depending rock arm 72. and provided at its free end witha buckling roller h which rests upon the pile of paper. The upperend ofthe depending rock arm is secured to the front end of the rock shaft Fso that a forward and backward movement is imparted to the bucklingfinger. The roller of the buckling finger is journaled in the bifurcatedfront end of the finger in the usual manner so that it is held againstturning during the forward movement of the buckling finger, so as tobuckle the sheet, and allowed to revolve during the backward stroke ofthe buckling finger.

7&2 represents a tension rod secured with one end to a swivel post Itpivoted on the lower portion of the depending rock arm h and passingwith its opposite free end loosely through a perforated ear 72 formed inthe upper side of the buckling finger.

71 represents a spiral spring surrounding the tension rod between theear 7& and a thumb screw 72. arranged upon the tension rod. By shiftingthe thumb screw upon the tension rod the pressure of the buckling rollerupon the sheet can be regulated.

7L Figs. 3 and 9, is a rearwardly projecting nose formed on the bucklingfinger on one side of its pivot and adapted to engage against the underside of a nose It formed on the depending rock arm 72, whereby thebuckling linger is raised from the sheet during the last portion of itsinward or forward movement. In the outer position of the rock armrepresented in Fig. 9, the nose of the rock arm, stands above the noseof the buckling finger. As the rock arm swings inwardly its nose ap*proaches the nose of the finger and finally presses down upon the noseof the finger and raises the inner end of the finger and its roller fromthe paper.

I represents the holding down finger, arranged a short distance in frontof the buckling finger and against which the sheet is buckled by theforward movement of the buckling finger. The holding down finger has avertical movement toward and from the surface of the pile of paper andis provided with actuating mechanism wherebyit is held down on the paperduring the operation of buckling, and lifted therefrom just before theadvancing buckling finger reaches it, so as to allow the latter to passunderneath. The

IOC

holding down finger is secured to the lower end of an upright rod 2'which slides vertically in perforated lugs t" formed on the carryingheadE. t represents a horizontal rock arm which is pivoted with its outerend to the carrying head while its inner end is bifurcated and engageswith sockets or shoulders formed on a sleeve 2' secured to the rod ofthe holding down finger. The latter is yield- .ingly held-in a depressedposition by a spring 13 attached with its ends to the horizontal rockarm i and the depending rock arm carrying the buckling finger.

2' represents a link whereby motion is transmitted from the rock arm ofthe buckling finger to the holding down finger. This link is pivotedwith one end to a forwardly and upwardly projecting lug i formed on thedepending rock arm h and provided at its opposite end with a bifurcationwhich receives a pin 2' formed on the horizontal rock arm 9?. During thelast portion of the forward stroke of thebuckling finger the lower endof the bifurcation in the link i strikes the pin i swings the horizontalrock arm 2' upwardly and thereby raises the holding down finger from thepile.

J represents a vertically movable gage foot which bears upon the cornerof the pile of paper and which performs the double function of holdingthe pile in place while the top sheet is being removed, and ofregulating the upward feed motion of the pile supporting table. Thisgage foot is provided with a vertical stem or rod j, which slides inperforated ears j 7' formed respectively at the upper and lower ends ofthe carrying head E. During the forward movement of the buckling fingerthe gage foot rests loosely upon the sheet so as to allow the advancingbuckling finger to draw the sheet from underneath the gage foot andafter the sheet has been withdrawn from underneath the gage foot thelatter is pressed 'upon the pile.

K is a horizontal rock arm pivoted with its outer end to the carryinghead and provided with a bifurcated inner end which engages with socketsor shoulders formed on a sleeve K. The latter slides lengthwise on therod of the gage foot below the upper earj.

K represents a clutch sleeve arranged upon the gage foot rod andyieldingly connected with the sleeve by a spiral spring 1: surroundingthe gage foot rod. The lower portion of this sleeve tapers downwardly.

10 represents a clutch platesurrounding the lower portion of the gagefoot rod above the earj and provided with an upwardly extending lip 70which latter is inclined on its rear side. In the normal position of theclutch plate it is free to move lengthwise upon the gage foot rod butupon tilting the plate it bindsagainst the gage foot rod and is heldimmovably thereon. The clutch plate is provided with a rearwardlyprojecting lug k which engages with a vertical guide groove or way 10formed in the carrying head, whereby the clutch plate is held againstturning and its upward movement is limited, as represented in Figs. 10and 11.

19 represents a lower spring surrounding the gage foot rod and bearingwith its ends against the ear 7' and the lower side of the clutch platewherebythe latter is raised until the lug k strikes the upper end of thegroove 10 During the first portion of the downward movement of thesleeve 70 the upper spring k is free from strain and causes the conicalsleeve 10 to move downwardly with the sleeve is until theconicalsleeveengages with the inclined lip of the clutch plate; When this takes placethe conical sleeve presses the upper end of the inclined lip forwardly,whereby the clutch plate is slightly tilted upon the rod and bound ortightened on the same, thereby holding the clutch plate and conicalsleeve against downward movement on the gage foot rod. This causes thefinal portion of the downward movement of the sleeve 70' to compress andstrain the upper spring k which pressure is transmitted to the gagefoot. During the first portion of the upward movement of the uppersleeve it it travels alone until the pressure is entirely removed fromthe conical sleeve and during the final portion of its upward movementthe conical sleeve is .raised and'disengaged from the lip of the clutchplate which loosens the latter on the gage foot rod. After the clutchplate has been loosened from the gage foot rod the gage foot again restsloosely upon the pile and the gage foot rod is' permitted to slidedownwardly through the clutch plate to the extent of the thickness ofthe sheet which has been removed from the top of the pile.

L represents a link pivoted with its lower end to a short arm Z formedon the depending .rock arm h at right angles thereto. The upper end ofthis link is provided with a longitudinal slot Z which-receives a pin Zarranged on the rock arm it. During the forward movement of the bucklingfinger the link L is carried downwardly and when the sheet has beendrawn from underneath the gage foot the upper end of the slot in thelink L strikes the pin Z and carries the rock arm is and sleeve 70downwardly thereby applying pressure upon the gage foot. During thereturn stroke of the buckling finger the rock arm 70 is raised by aspring Z secured with its ends to the rock arm is and an upwardlyprojecting lug Z formed on the head.

The mechanism whereby the feed table is raised automatically, isconstructed as follows and as most clearly shown in Figs. 3, 7, 8, 9,15,16, 17,18, and 19: M represents a longitudinal rock shaft journaledin bearingsm m formed, respectively, in the carrying head and frame, andprovided in frontof the car-- rying head with a rock finger m The freeend of the rock finger is provided with an adjusting screw m which isadapted to bear upon a horizontal gage arm'm secured to the upper end ofthe gage foot rod. This gage arm is guided in its vertical movement withthe gage foot by a bifurcated jaw m formed on the upper ear j of thecarrying head. N represents a rock shaft arranged transversely in themachine above the longitudinal shaft M, and journaled in a bearing 77.formed on the inner side of the carrying frameF and bearings n 71secured to the top of the side frame of the machine. The longitudinalrock shaft M is provided in rear of the bearing m with a segmental gear01 which meshes with a similar segmental gear 01 on the transverse rockshaft N. The teeth of these segmental gears are arranged on a skew bevelowing to the difference in the planes of the longitudinal and transverserock shafts M N. a represents a peripheral cam formed on the innerportion of the groove cam and bearing against a roller it pivoted to thefree end of the segmental gear 72. whereby the rock finger is raisedfrom the gage arm. lVhen the peripheral cam has passed the roller n thesegmental gear 77. is drawn downwardly by a spring n secured with itsends to the carrying frame F and a rearwardly projecting nose a formedon the segmental gear a which causes the rock finger to descend until itstrikes the gage arm. 0 represents an upright stop arm which is mountedupon the outer end of the transverse shaft N and which is provided onits front side with a vertical series of ledges or stops 0'. 0represents an elbow lever pivoted on the shaft 19 and provided on itsupwardly projecting arm 0 with a pawl 0 which engages with a ratchet rim0 formed on the periphery of the bevel wheel I). Thelower rearwardlyprojecting arm 0 of the elbow lever 0 is provided with a roller 0adapted to bear against a cam o secured to the end of the counter shaftg. This arm 0 is also provided with a bearing piece 0 which overhangsthe stop arm and is adapted to engage with one of the ledges of thelatter. The revolving cam 0 always raises the rear arm of the elbowlever to the same point for the purpose of rotating the ratchet rim 0but the downward movement of the elbow lever is variable and iscontrolled by the position of the stop arm. \Vhen the latter is in itsrearmost position the rear arm of the elbow lever is permitted to dropto its fullest extent causing the elbow lever to be subsequently raiseda full stroke by the cam 0 lNhen the stop arm is moved forwardly thebearing piece of the elbow lever strikes one of the ledges on the stoparm and reduces the backward movement of the elbow lever so that thelatter will be moved forwardly only a part of its fullest stroke by thesubsequent rotation of the cam 0 After each time that the elbow leverhas been raised by the cam o the peripheral cam 12 rocks the transverseshaft N and moves the stop arm forwardly underneath the bearing piece ofthe elbow lever but the return or rearward movement of the stop arm iscontrolled by the rock finger of the longitudinal rock shaft M whichbears on the gage arm of the gage foot.

In the normal position of the pile of paper the descent of the rockfinger is so small that the stop arm is moved rearwardly onlysurficiently to permit its highest ledge to be presented to the bearingpiece of the elbow lever so that the cam 0 will not move the elbow leverforward. Then a sufficient number of sheets have been fed from the pileso that its surface is below the proper position,the rock fingerdescends a greater distance which causes the stop arm to move rearwardlya corresponding distance and present a lower ledge to the bearing pieceso that the backward throw of the elbow lever is increased. As the feedtable is gradually raised the downward movement of the rock finger isagain gradually reduced until the surface of the paper is in its normalposition. If the feed table is lowered to renew the supply of paper whenthe rock finger and elbow lever are in their lowest positions asindicated by the dotted lines Figs. 9 and 16, the subsequent raising ofthe feed table likewise raises the rock finger and causes the stop armto press against the bearing piece of the elbow lever through the mediumof the rock shafts M N and gage foot.

In order to prevent breakage and permit the rock finger to rise when theparts are in this position a yielding connection is formed between thetransverse rock shaft N and the stop arm which is constructed asfollows:- P represents a carrying arm which is secured to the transverserock shaft N between the bearings n if. The free end of this carryingarm is provided with a segmental guide rod 19 which slides through aperforated ear 19 secured to the inner side of the stop arm. The stoparm is mounted loosely on the transverse shaft N and the carrying arm isyieldingly held away from the stop arm by a spiral spring 9 whichsurrounds the segmental guide rod and bears with its ends against thecarrying arm and the rear side of the ear of the stop arm. The expansionof the spring 19 is limited by a pin 19 arranged in the segmental rodand bearing against the front side of the ear on the stop arm.Asufiicient tension is placed upon the spring 19 to hold the stop armand carrying arm sufficiently rigid upon each other under ordinaryconditions, but when the rock finger is raised, while the forwardmovement of the stop arm is prevented by the bearing piece of the elbowlever, the spring 19 is compressed which prevents any of the parts frombeing broken. As soon as the elbow lever is raised during its nextforward throw the spring 19 expands and returns the stop arm to itsnormal position. The segmental gear 02 is secured to the longitudinalshaft M, so as to turn with the same, and to the carrying frame F, so asto be held against lengthwise movement on said shaft, by a feather g.This feather is of the same construction as that shown and described inLetters Patent No. 434,649, dated August 19,1890, granted to W.\Vomcrsley to which reference may be had for a more complete descriptionthereof. The segmental gear a is secured to the transverse shaft N, soas to turn therewith, and to the carrying frame, so as to movetransversely therewith, by a feather q. The feather q is constructed thesame as the feather g. g represents a nose formed on the front portionof the segmental gear n and adapted to bear against a stop g formed onthe front side of the bearing 9 whereby the segmental gears are limitedin their upward movement and thereby prevented from becoming disengaged.

R, Figs. 4, 7, 8 and 15 represents the feeding fingers whereby the topsheet is removed from the pile to the tapes r which deliver it to theprinting press or other machine. The free front end of each feedingfinger is prov1ded with a roller similar to the buckling finger. Thefeeding finger is pivoted with its rear end to an arbor 'r' arranged onthe lower end of a depending rock arm 1*. This rock arm is adj ustablysecured by a feather r and set screw r to a transverse rock shaft rjournaled in bearings a formed in the upper ends of the side frames. Arocking motion is imparted to this shaft by a crank r secured to theadjacent end of the counter shaft and connected with a rock arm r of thetransverse shaft r by a link r as represented in Fig. 3. Pressurev isapplied to each feed finger by a spiral spring 0" surrounding the arborr and bearing with its ends against a pin 0" arranged on the feedingfinger and a pin r 'arranged on a sleeve r secured to the outer end ofthe arbor.

S represents a lifting shaft arranged over the feed finger shaft andjournaled in bifurcated bearings 8 formed at the upper ends of eachdepending rock arm r 5' represents a lifting rod pivoted with its 4lower end to the feeding finger and passing loosely with its upper endthrough a longitudinal slot .9 formed in the rear end of a lifting arm 8The latter is secured by a feather s to the lifting shaft between thebifurcated bearings s which compels thelifting arm to rock with thelifting shaft and also move lengthwise upon the same upon shifting thefeeding fingers transversely in the machine.

s is a thumb nut applied to the upper screw threaded end of the liftingrod and bearing against the upper side of the lifting arm. A rockingmotion is imparted to the lifting shaft in one direction by means ofacam s on the shaft gand which engages against a rock arm 5 secured tothe end of the lifting shaft, and in the opposite direction by a spring8 During the forward movement of the feeding fingers they are in contactwith the surface of the pile and push the top sheet from the pile. Atthe end of the forward stroke the feeding fingers are raised quickly innearly a vertical line by the cam s so as to offer no resistance to thesheet which is being carried oif the pile. The feeding fingers are heldin this raised position until they arrive at the end of their backwardmovement when the cam 3 again lowers them upon the pile of paper.Heretofore this feeding finger has been raised by the mechanism shown inLetters Patent, No. 434,649, dated August 19, 1890, but in thatmechanism a lifting rod is guided in a lug, on the depending rock arm,and is liable to be cramped or eventually bent or broken by the actionof the lifting plate engaging against the hook shaped upper end ofthelifting rod. In ourimproved construction this diificulty is avoided.

T represents the main driving shaft of the paper feeder which isjournaled in bearings t t arranged on the rear ends of the side frames,and t is a sprocket wheel which is secured to one end of said shaft andto which motion is transmitted from a sprocket wheel 6 mounted on theprinting press shaft t by a chain belt t as shown in Figs. 1 and 2.

t represents a gear wheel secured to the opposite end of the drivingshaft and which transmits motion to the gear wheel t on the end of thecounter shaft g, by means of an intermediategearwheelt Theintermediategear wheel i is mounted on an adjustable arm i which latter is pivotedon the main frame concentric with thecounter shaftg and provided with aconcentric slot 25 t represents a screw-threaded stud arranged on themain frame and passing through the slot Z of the adjustable arm, and 25is a clamping nut which is arranged on said stud and which bears againstthe arm t? for holding it in its adjusted position. The ad j ustable armt permits the gear wheel i to be shifted concentrically with referenceto the gear wheel t thereby. allowing the gear wheel t to be changed fora larger or smaller wheel in order to increase or decrease the speed ofthe buckling mechanism.

u represents the longitudinal side bars of the tape frame which arepivoted with their front ends upon the driving shaft T, and

are connected at their rear ends by a transverse feed board to. nrepresents a receiving roller which is mounted loosely upon the drivingshaft so as to revolve thereon- The tapes pass with their receivingportions around the receiving roller, thence rearwardly with their upperportions and around a ,delivery roller u arranged adjacent to the feedboard and journaled in bearingsformed in the side bars to. I v

n represents guide wheels which are hung upon the front cross rod a byarmsu and which rest upon thetapes as they pass around the receivingroller. When the sheet has been deposited by the feeding fingers uponthe tapes the latter carry the sheet forwardly until it strikes thefront registering guides to".

These front guides are hung upon a cross bar a of the printing press orany other suitable part ofthe press frame. I

,Whenthe paper feeder is arranged at aconsiderable distance from theprinting press, a

long tape mechanism can be employed which runs comparatively slow andallows ample time for registering the sheet before it is carried intothe printing press; but where economy in room is a necessity the paperfeeder must be arranged closer to the printing press, therebynecessitating shortening of the tape mechanism.

In order to gain sufficient time to register the sheet upon the tapesand deliver it to the press before another sheet is discharged upon thetapes, the speed of the latter must be increased in proportion to thedecrease in the distance between the feeder and the press. Thisincreased speed of the tapes is effected by rotating the receiving taperoller faster than the shaft on which it is mounted, by the followingmechanism:-V represents a short counter shaft which is journaled in amovable bearing 1) provided with arms 1;, hung upon the driving shaft Tso as to swing concentric therewith. The outer end of this counter shaftis provided with a small gear wheel '0 which is driven from the largergear wheel i on the adjacent end of the driving shaft, by anintermediate gear wheel '0 which latter meshes with both gear wheels'1)", and 25 and is journaled upon a bracket 0 secured to the sideframe. The inner end of the counter shaft V is provided with a sprocketwheel '0 which transmits motion to the receiving roller 10 by a chainbelt 12, running around the sprocket wheel '0 on the counter shaft, anda similar sprocket wheel 12 secured to the adjacent end of the receivingroller of the tapes. The gear wheel 11 at the outer end of the countershaft can be changed for one of larger or smaller size, according to theincrease in speed it is desired to give to the tapes with reference tothe driving shaft. Upon changing the gears on the counter shaft, thelatter is swung toward or from the intermediate gear wheel '0 concentricwith the driving shaft, thereby avoiding disturbance of any other partsof the driving mechanism. One of the arms 4; is provided with anupwardly extending adjusting bar '0 having a slot '0 curved concentricwith the driving shaft. The counter shaft is secured in its adjustedposition by a clamping bolt 2: arranged upon the main frame and passingthrough the slot '0 of the adjusting bar '0 In order to increase thefrictional contact between the sheets of paper and the tapes upon whichthey rest, when no upper tapes are used, we employ the followingmechanism, which is represented in Figs. 1, 2, 13, and 14:: W representstwo pressure rollers which bear upon the carrying portions of the tapesbetween the receiving and delivery rollers. As the sheet is carriedforward by the tapes, it is pressed down upon the latter, thereby,increasing the frictional contact between the tapes and the sheet andenabling the latter to be carried forwardly more positively. Thepressure rollers also prevent the sheet from backing up upon strikingthe front guides, thereby registering the sheets more accurately. Eachof the pressure rollers is jonrnaled upon an arbor 10 having acontracted shank which passes through slots '10 formed in two clampingplates 20 The arboris held in position byashoulder w bearin g againstone of the clamping plates and a thumb nut 20 arranged upon the shankand bearing against the other plate. The clamping plates are provided ontheir upper and lower ends with jaws 10 which are clamped againstopposite sides of theup' per and lower bars of the supporting frame wThe pressure rollers can be adjusted vertically by raising or loweringthe shanks of the arbors in the slots of the clamping plates, and canalso be adjusted lengthwise of the tapes by shifting the clamping plateslengthwise upon the supporting frame. The thumb nut to serves the doublepurpose of holding the clamping plates upon the supporting frame andholding the pressure rollers upon the clam ping plates. X representshangers which support the front portions of each frame and which aresecured with their upper ends toa crossrodzr. Thelatteris supportedatits ends upon standards 50 secured to the side bars of the tape frame.The lower portion of each hanger is provided with an opening in whichthe front portions of the two bars, constituting each supporting frame,are secured. The ends of the two bars are arranged one upon the other inthe cavity formed in the lower portion of the hanger and are clampedtherein by a thumb screw or. The rear end of the lower bar is curvedupwardly and secured to the upper bar and the latter is supported on thecross rod of the printing press.
